In davisson germer experiment an electron beam accelerated with 54v is diffracted at an angle of 5? by nickel crystal and produces 1st diffraction maxima the inter atomic distance in nickel is ?

Dear Student

in your question, value of angle is not clear (5 ?)

I solving it by assuming it as 50 degree in place of question mark

Hope it will help you

Looking forward to hear from you again
